    The inverse is (x-2) / 4

    Step-by-step explanation:

    f (x) = 4x+2

    y = 4x+2

    Exchange x and y

    x = 4y+2

    Solve for y

    Subtract 2 from each side

    x-2 = 4y+2-2

    x-2 = 4y

    Divide each side by 2

    (x-2) / 4 = 4y/4

    (x-2) / 4 = y

    The inverse is (x-2) / 4
